- One other (actually, the major) point that I missed in my reply to Dieter
- Kollers article extolling the virtues of old-time design is simple:
-
- Engineers designed systems they way they did not because they wanted to,
- but because they had no choices. Speaker efficiency had to be high to get
- any acceptable levels from low-power amplifiers not because anybody though
- that that was a good idea, but because they did not know how to design
- higher power amplifiers. Speakers were made with witche's brew pulp cones
- that had terrible internal damping, varied all over the place in
- manufacturing, changed their characteristics with the slightest change in
- temperature and (especially) humidity and age not because they knew it was
- the best way to do it, but because they didn't know any better.
-
- You may well be right in saying that it's difficult to design clean
- high-power amplifiers these days. But in doing so you must also realize
- that back then it was simply impossible. People didn't refrain from
- designing high power amplifiers back then not because it was difficult or
- not a good ide, but because they didn't know how.
-
- Now there may be some comforting nostalgia in listening to these systems
- (which, by the way, sound radically different then they did back then,
- the equipment (especially loudspeakers) did not age gracefully for the
- most part). And we can certainly say that some of these systems were the
- very best in their day, and the people back then lived in a naive sense
- that things were just great.
-
- But the assertion that the loudspeaker engineers of the '50's and before
- somehow knew more than we do today is most amusing, especially to those
- same engineers (many of whom I know personally), is absurd.
